In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.刑满释放人员张浩误打误撞与文物巨盗黑龙互换身份，在警察董政的配合和指导下，张浩与犯罪分子斗智斗勇，经历了一系列啼笑皆非的对抗之后，最终警民配合破获一起惊天文物倒卖案件。钱多钱少都不要紧，重要的是那份心意。为了取回菜谱bon，保护大家好吃的Egao，与bundle团对抗！Please create a Die class that contains an attribute named sides with a default value of 6.

Due to Aban's years of experience in China, his rather sophisticated treatment of people and his reputation as a Times, he has made quite a wide range of friends. He and Chiang Kai-shek's wife Song Meiling are also very close friends. He doesn't have to be like me. As a reporter of the Japanese News Agency, he has to be busy with the morning and evening reports every day. He just needs to pick up some important information and transmit it. So he is in an extremely advantageous position. Although I am in Shanghai, I have always been concerned about the U.S. Policy towards Japan and developments towards China, so I often exchange views and intelligence with Aban.
